苹果的WWDC ，除了发布了os x 10.10 和IOS8 外，还推出了Swift。详细点击这里

代码总体风格有点像Java，也有点像javascript。

下面给出一些代码段（来自苹果官方手册）：

println("Hello, world")

“var myVariable = 42
myVariable = 50
let myConstant = 42”

“var shoppingList = ["catfish", "water", "tulips", "blue paint"]
shoppingList[1] = "bottle of water"
 
var occupations = [
    "Malcolm": "Captain",
    "Kaylee": "Mechanic",
]
occupations["Jayne"] = "Public Relations”

“let vegetable = "red pepper"
switch vegetable {
case "celery":
    let vegetableComment = "Add some raisins and make ants on a log."
case "cucumber", "watercress":
    let vegetableComment = "That would make a good tea sandwich."
case let x where x.hasSuffix("pepper"):
    let vegetableComment = "Is it a spicy \(x)?"
default:
    let vegetableComment = "Everything tastes good in soup."
}
”
